Open-Source AI Agent Frameworks

Superpowers adds a development workflow to AI coding assistants. It's for developers who want to approve a design before implementation and have the agent work through a plan with testing and review.

Paperclip coordinates AI agents for people managing work across development, research, marketing and other business functions. It gives the team a shared structure and keeps its work tied to organization goals.

OpenAI Agents SDK is a Python framework for developers building tool-using agents with local models or cloud APIs. It supports gpt-oss through Ollama, with LM Studio also documented as a local model option. OpenAI models use the remote Responses API by default and require an API key, even when the agent runtime and workspace run on your machine.

Exo Agent Framework is for developers building long-running AI agents that can revise their own code, tools and prompts. It preserves agent identity and history as their behavior changes across runs.

HarnessX is a Python framework for developers building AI agents whose behavior they can reuse and adapt. It separates model choice from tool use, memory and context handling, so changing an agent's role doesn't require rewriting it.

AutoAgent lets people create AI agents by describing the work they want done. It's for users who want custom agents without writing the agent code themselves, or a ready-made research assistant for gathering information and producing reports.

CrewAI is a Python framework for developers automating work with teams of AI agents. It combines agents that make decisions with explicit workflow logic, so a process can include both autonomous work and predictable steps.

Optio coordinates coding agents and automated work for teams using their own infrastructure. A shared feed tracks pull requests, recurring jobs, interactive sessions and agents that stay available between tasks.

Yuxi is a self-hosted AI agent platform for teams that need answers from their documents and agents that can carry out multi-step work. Its browser workspace brings knowledge sources, task progress and generated files into the same conversation.

agentchattr is a local chat server for developers coordinating multiple AI coding agents. Humans and agents share a conversation and can mention one another to trigger responses without carrying messages between terminals.

iCode is a terminal development workspace for developers who want to work with AI agents and inspect their changes. It brings conversations, agent workflows and a working shell into one interface.

PraisonAI is a Python framework for developers building AI agents that research, write code, or carry out tasks across apps. It supports single agents and coordinated teams for work that needs several steps or specialist roles.

Team Tasks is a local command-line tool for developers coordinating AI agents through OpenClaw or another orchestration system. Shared JSON files keep task assignments, progress and results in one project record.

LangBot is an AI bot platform for teams handling customer support, internal questions, or community chats. It brings agents and existing AI workflows into the messaging services people already use.

Open Multi Agent is a TypeScript framework for developers building self-hosted AI agent teams. It lets you coordinate work across agents, require human decisions before consequential actions, and inspect what happened afterward.

AutoGen is a framework for cooperating AI agents, with local Playwright browser automation, code execution and an experimental OllamaChatCompletionClient for local models. Its orchestration can run on your machine or across servers. Standard OpenAI and Azure OpenAI service connections send model requests to remote services; compatible endpoint overrides are separate configurations.

RESTai is a self-hosted AI platform for developers and teams building document assistants, agents and AI services for other applications. Its web interface manages projects with separate models, prompts and tools, plus a chat playground for testing them.

BotSharp is a C# framework for .NET developers building AI assistants into business applications. It coordinates agents with different responsibilities and keeps track of conversation state.

Cheshire Cat is a Python framework for learners, researchers and creatives building custom AI assistants. It supports hands-on experiments through a web chat interface and an API. It isn't recommended for production use because it's unstable and may have breaking changes or incomplete features.

DocsGPT helps teams search company documents and build AI assistants that answer from those materials. It can run inside your network with local models, including an air-gapped deployment where documents and questions stay within that network.

AgentFlow is a Python framework for developers coordinating coding agents across tasks that depend on one another. It runs Codex, Claude, Kimi, and Pi agents in workflows that can split work and bring the results back together.

YoMo is a self-hosted framework for developers building AI agents that call application tools. It supports distributing inference and tool execution across locations closer to an application's users.

Agently is a Python AI agent framework for developers building assistants and service backends with local Ollama models or hosted model APIs. It runs within your application, without requiring a separate orchestration service. Model requests go to the endpoint you choose, so using a remote provider sends the request data outside your machine.

Waku Agent is a personal AI assistant that runs on your laptop, stores its memory locally and calls remote model providers. It's for developers who want to inspect and change the assistant's behavior in Python. The agent uses provider API credentials for reasoning; requests to cloud providers are processed by those services.

OwnPilot is a self-hosted AI assistant for people who want personal records and agents that can carry out tasks in one web interface. It supports local model backends as well as cloud providers.

ZeroClaw is a personal AI agent for people who want an assistant running on their own computer or server. It can use a shell and browser, respond through messaging apps and perform scheduled tasks.

Hatice is a self-hosted coding agent orchestrator for developers who want agents to work through issue-tracker tasks. It assigns issues to Claude Code agents and manages work across multiple turns.

LangGraph is an AI agent framework for developers building applications on their own machines, including workflows that use local models through LangChain's ChatOllama integration. Ollama can run models such as gpt-oss locally. LangGraph also works with remote model providers, so where model requests go depends on the connection your application uses.

Agent S is a computer-use AI agent framework for developers and researchers building desktop automation. It takes natural-language tasks and operates desktop and web applications through their screen interfaces, without requiring an API integration for each app.

Fast Agent is a terminal coding assistant and Python toolkit for developers building AI agents and automated workflows. You can choose local LLMs or hosted providers and use the same toolkit for interactive work, scripting, and evaluation.

Nexent is a self-hosted AI agent platform for people and teams who want to build agents by describing tasks in plain language. It generates executable agents without requiring code or a visual workflow editor.

Microsoft Agent Framework is an AI agent framework for developers building locally hosted applications in Python or C#/.NET. It supports local development and self-hosting of the application, while integrations such as Azure OpenAI and OpenAI send model requests to those providers. Self-hosting the app doesn't make those calls offline or remove provider costs.

AgentArk is a self-hosted AI agent runtime for people who want a personal assistant that remembers preferences and carries out ongoing work under their control. It runs through Docker on macOS, Windows and Linux, with a browser interface for chat, tasks and action review. It's free and open source under Apache 2.0.

Agent Zero is a self-hosted AI agent framework for people who want an assistant to carry out research, coding, and document work on a computer. You can watch its actions and intervene in the same desktop with your mouse and keyboard.
